Overview

The LB1863M and LB1869 (LB1669M) are 2-phase unipolar brushless motor drivers that are provided in a miniature flat package that contributes to end product miniaturization and supports automatic mounting. These products support the implementation of motor drive lock protection and automatic recovery circuits, and alarm specifications with a minimal number of external components.

Features and Functions

• Hall elements can be connected directly to the IC itself.

• 1.5-A output current output transistors built in

• Rotation detection function that provides a low-level output during motor drive and a high-level output when the motor is stopped

• Motor lock protection and automatic recovery functions built in

• Thermal shutdown circuit

• Switching noise can be reduced with an external ceramic capacitor.
